Answer this question truthfully
### Question: What causes Carbuncle?
### Response: Most carbuncles are caused by the bacteria staphylococcus aureus. The infection is contagious and may spread to other areas of the body or other people.
A carbuncle is made up of several skin boils (furuncles). The infected mass is filled with fluid, pus, and dead tissue. Fluid may drain out of the carbuncle, but sometimes the mass is so deep that it cannot drain on its own.
Carbuncles may develop anywhere, but they are most common on the back and the nape of the neck. Men get carbuncles more often than women.
